Determining the potential impact of a micro heat pump for domestic water heating
(2002)
Hot water used in the South African domestic sector is mostly heated by in-tank electrical resistance heaters. These so-called "geysers" are the major contributors to the undesirable high morning and afternoon peaks imposed ...
Techno–economic comparison of power conversion units for the next generation nuclear plant
(North-West University, 2005)
The choice of thermodynamic cycle configuration is a vital first step in the development of a new nuclear power plant. Various cycle configurations for High Temperature Gas Reactor power conversion are under investigation. ...
DSM opportunities in underground refrigeration systems
(North-West University, 2008)
This study will focus on the feasibility of demand side electricity management on
underground refrigeration systems. It will include a relevant literature study, the
investigation process, a simulation model, expected ...
Thermal stress evaluation of thermo-blast jet nozzle materials
(North-West University, 2004)
In the last few years a new method for surface preparation has evolved, namely thermo-abrasive blasting. This technique utilises a high enthalpy thermal jet to propel abrasive particles. The thermo-abrasive blasting gun, ...
A comparative study into the application of the NRS 048, IEEE 519-1992 and IEC 61000-3-2 on harmonic apportioning in a discrimitive tariff
(North-West University, 2003)
Development in power electronics enabled sophisticated energy conversion. These new solid-state energy conversion processes are energy-effective, but are inherently non-linear which means that the load current is typically ...
Optimising the operation of underground mine refrigeration plants and ventilation fans for minimum electricity cost
(North-West University, 2003)
This study describes the development and use of a mathematical model that will enable mine operators to
minimise the costs of electricity consumed by the ventilation and refrigeration systems used for
environmental control ...
Neural network inference measurements applied to the pebble bed modular reactor
(North-West University, 2004)
Inference measurements with time-delayed feed-forward neural networks facilitates the
inference of unknown variables from known variables in non-linear dynamic systems. This
is based only on the mapping data of the known ...
The use of neural networks to determine the long-term impact of demand side management
(North-West University, 2003)
Eskom, South Africa national electricity provider, estimates that in the year 2006
South Africa will experience a capacity shortage. One way to address this problem is through the implementation of Demand-Side Management ...
The conceptual design and development of a micro gas turbine generator
(North-West University, 2006)
All over the world interest in small scale stand alone power generators is growing. This interest is motivated by lower electrical costs and/or the capability to be unaffected by power failures and blackouts that could ...
The development of a multimedia reader for distance learning
(North-West University, 2005)
The goal of this project was to produce a device which can provide distance learning students with a method of learning by means of enriched study material. This device must be able to display study material in the form ...
